STEAM OR HOT- \NATER RADIATOR.

SPECIFICATION forming part of Letters Patent No. 6 01, 656, dated April 5,1898.

Application filed April 12 1897. Serial No. 631,706. (No model.)

To all whom, it may concern:

Be it known that we, JOHN THOMAS J ACK- SON,mechanical engineer, and FERGUS JAMES TRAVERs,'subjects of the Queen of Great Britain, residing in the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Steam or Hot-Tater Radiators, in which a positive and constant circulation of steam and hot water is sustained, of which the following is a specification.

This invention relates to certain new and useful improvements in or relating to steam and hot-water heating-radiators; and the objects of the invention are as follows: first, to provide 'a radiator with a direct circulation and one having a uniform temperature throughout its entire length; second, to provide a radiator that is adapted for use either in a verticalor horizontal position and one .so constructed that in either position the same-will drain and ventilate; third, to provide a radiator having at the top of the loops thereof a transverse passage connected at either end by vertical passages with the upper chamber of the loops, and said transverse passage is also connected with longitudinal passages and by means of the said passages thestagnant air may be drawn off the entire radiator whether the same is placed in a ve'rtical or horizontal position and whether the radiator-loops are placed on their side or their edge; fourth, to provide a radiator having at its feed end four connections-drainage and feed connections on one leg of the loop and feed and drainage on the otherthe same being arranged alternately; fifth, to provide aradiator that is especially constructed for use in a room where the radiator cannot be used in a vertical position, but only in a horizontal position, such as under the floor, and one that is so constructed that it can be fed, drained, and vented while in a horizontal position and one that will be of a uniform temperature throughout and free from aircushioning; sixth, to provide a radiator-loop having at each side thereof two connections at the top and two at the bottom that are in circulation with each other and with the interior chambers of the said loops; seventh, to provide a radiator-loop having drainage,

fed whether in a vertical or horizontal position; eighth, to provide a radiator that is hot-water system;

The invention consists, essentially, of the device hereinafter more fully set out and more particularly pointed 'outin the claims.

In the drawings, Figure 1 shows a face view, out in section, of a circulating loop or column. Fig. 2'shows an edge view, out in section, of a circulating loop or column. Fig. 3 shows several loops of the radiator arranged in position. Fig. 4 shows a top cross-sectional view of-the air-vent. Fig. 5 shows'a crosssectional view of the drainageand feed.

Like letters of reference refer to like parts throughout the specification and drawings.

0 represents one of the loops in which are formed two chambers or water-legs e and c. The water-leg e is located in the feed side of the radiator-loop and the, water-leg e in the return side of the radiator-loop. The entrance to the water-leg e is surrounded by a hub t, Fig. 2, said water-leg '6 commencing with a right-angle bend or elbow atthe bottom of the radiator-loop and is in circulation with the water-leg e at d. The waterleg e terminates or ends at the lower and return end of the radiator-loop at a with a rightangle bend in the opposite direction of the right-angle bend at the beginning of the waterleg 6 and at the oppositeside of theloop from the feed-openin g a. At the bottom of the said loopO is a brace X, holding the lower ends of the loop rigid. Within said brace X is an interior passage 8, which said interior passage s is in circulation at the lower end'of the radiator-loop with the water-legs e and e at the right-angle bends or elbows.

At the extreme bottom of the water-legs c and e and on the opposite sides to the ports a and a are placed small hubs n and n with passages therein in circulation with the water-legs e and e at the back of the right-angle bends in said water-legs.

equally adapted for use either in a steam or The hub t is fitted with amale coupling 19,

which is adapted to fit into a female coupling 19 in hub t atthe return end of the water-leg e of the next adjacent loop. The female coupling 19 is adapted to receive a compressible ring or gasket to prevent leakage.

The hub n is fitted with a male coupling m, which is adapted to fit into a female coupling m' in hub 71/ at the return end of the water-leg e, which is on the opposite side from the feed-openin g a of the next adjacent loop.

. The female coupling m is adapted to receive a compressible ring or gasket to prevent leakage.

By means of the passage 3 the lower end of the water-leg eis placed in circulation with the lower end of the water-leg e, and the condensation from steam in the water-leg 6 can pass either through the opening 8 or around the end (1 into the water-leg e,and from thence through the drainage-openings s and s or through the return-port ct to the next adjacent loop and then to the flow or return pipe.

By means of the passages s, s, and s the condensation from steam or otherwise may pass from one end of the radiator to the other-that is, from the feed to the return end in casev the radiator is used on a twopipe system or from the return to the feed end in case the radiator is used on a one-pipe system-and by means of the said passages s,

s, and s" the said radiator can be drained of condensation and also can be emptied of water when desired. These radiator-loops are connected at the bottom in two places, the water-leg e of the loop 0 connecting with the water-leg e of the next adjacent loop, while the passage 8 at the lower end of the waterleg 6 connects with the passage 8 at the lower end of the water-leg e of the next adjacent loop. When the faces of aand a are brought together, the circulation between e and e of the next adjacentloop is complete, and when the faces of s and s are brought together the two form one continuous passage from c to e of the next adjacent loop, and this forms a drainage-passage for the several loops, and the radiator is connected alternately with feed and drainage on the one side and drainage and feed on the other.

The top of the radiator-loop is provided w th a transverse passage 0", in circulation with the water-legs e and e of the radiatorloop by means of vertical passages h and h.

The said transverse passage 1" is along the extreme top of the radiator-loop and runs at right angles with the water-legs e and e. The radiator-loop is also provided with longitudinal passages r and r, running at right angles with the transverse passage r,which said passages r and r" are provided at one end thereof with male couplings y and y, which are adapted to fit into female couplings z and 2 at the other ends of the said passages r and r of the next adjacent loop. The said passages r and 7" by means of the transverse passage rare in circulation with each other, and by means of the vertical passages h and h are in circulation with the water-legs e and e. The female couplings z and z are each adapted to receive a compressible ring or loop.

diator by an automatic valve placed on one,

of the end loops of the radiator. This radiator-loop may be made without the transverse passage 7" and the radiator will be properly ventilated by means of the vertical passages 71 and h and the longitudinal passages 71" and r.

In practice when the loops are placed together the male connections 19 of the hubt are inserted into the female connections p of the hub 25 ofthe next adjacent loop, a compressible ring or gasket being interposed between the male and female connections, and the male connections m of the hub n are inserted into the female connections m of the hub n of the next adjacent loop, a com pressible ring or gasket being interposed between the male and female connections. These two connections are at the bottom of the radiator- The male connections y and y of the hubs'k and 7c are inserted into the female connections 2 and z of the hubs ZandZ of the next adjacent loop, compressible rings or gaskets being interposed between the male and female connections. The hubs 7s and 7c and land Z are at the top of the radiator-loop. The coupling-nut or other coupling medium is then tightened and the adjoining loops forcibly brought together, causing the male connections to force the compressible rings into the female connections, thus preventing any leakage from any of the said openings.

The end loop of the radiator may be provided with an automatic valve for venting purposes.

The circulation of the water or steam isas follows: The water enters the loop 0 at the port a, passes through the ri ht-angle bend at the bottom of the water-leg e, up the waterleg (2 around cl into the water-leg 6, down the water-leg e to the right-angle bend at the bottom or end thereof, out through the port a into the port a of the next adjacent loop, and so on to the end loop of the radiator, when it discharges into the return-pipe.

When the radiator is used in a horizontal position, or lying flat, the ports ct and ct will alternately be on the upper side of the radiator, and through the tubular passages s, s, and s the water caused by the condensation of steam or otherwise will pass from one loop into the other and through said ports to the flow or return pipe, according as the radiator is used on a one or two pipe system, and by means of the said passages s, s, and s" and the ports a and a the radiator can be entirely emptied of water when not in use.

The fact of being able to drain from the lowest point and on either side of the loop causes this radiator to be used to advantage in either a vertical or horizontal position and enables the condensation to be drained off the radiator in either position.

The vertical passages h and h being in air culation with the water-legs c and e and also in circulation with the longitudinal passages r and r the stagnant air may be drawn off the water-legs e and e at the highest point,

p and by this means prevent cushioning in the upper part of the loops, and thereby assist in a free circulation of steam or water.

The hubs t and i of the end loops of the radiatorinstead of being fitted with male and female connections are fitted to receive the flow or exhaust pipe, and the hubs n and n of the outer side of the end loops of the radiator are entirely removed, as the condensed steam passes in the end loop of the radiator to the flow or return pipe without the assistance of the drainage-openings.

Having now particularly described and ascertained the nature of our said invention, we hereby declare that what we claim is 1. A radiator having loops coil-shaped the water-legs thereof being in circulation at the top only, said loops having a transverse passage at the top of the loop and two passages vertical to the said water-legs and connected with the transverse passage at the top of the loop, one of said vertical passages being located at one side of the loops and the other at the other side thereof, substantially as set forth.

2. A radiator having loops coil-shaped the water-legs thereof being in circulation at the top only, having a transverse passage, and two vertical passages, and two longitudinal passages at the two upper angles of the radiator-loops at opposite sides thereof, and at right angles to the vertical and transverse passages and the water-legs, whereby when the several loops of the radiator are brought together the two longitudinal passages form two continuous parallel passages from one end of the radiator to the other in circulation with the water-legs of the several loops thereof by means of the transverse and vertical passagestherein, substantially as set forth.

3. The combination with the legs of the radiator-loop provided with transverse passages at their lower ends, of a brace connecting the legs and provided with a passage, substantially as set forth.

5. A radiator-loop provided with verticalair-passages arranged at opposite sides of the upper end of the loop; a longitudinal passage communicating with and connecting said vertical passages, transverse air passages arranged at right angles to the longitudinal passage and communicating with the latter; and

transverse and horizontal drainage-passages at the lower end of the loop and communicating with the water-legs of said loop, substantially as shown and described.

6. Aradiator comprising a plurality of loops each of which is provided at opposite sides of its upper end with two independent passages communicating with the water-legs of the loop; and at opposite sides of its lower end with two independent drainage-passages also in communication with the water-legs, substantially as shown and described.
